An integrated programme using EM on dairy farms has the potential to give significant improvements of environmental indicators. Research both from overseas and NZ comparing EM in various applications related to dairying, and some related research on some of the individual micro-organisms that are contained in EM, demonstrate significant benefits in mitigating some of the negative impacts on the environment.
The areas that we can influence positively with EM are:
Key applications for Dairy farming
With the addition of EM to the pasture we can expect an increase in yield (Daly & Stewart). This paper published in a refereed international journal showed that EM increased the yield of crops, and by assumption an increase grass growth could be expected with application of EM.
When EM is combined with a half rate of fertiliser, the production is similar to a full rate of fertiliser on its own. The EM contains phosphate solubilizing bacteria (PSB) this will mobilise P and enhance the breakdown of rock phosphate. The Photosynthetic bacteria have a denitrifying characteristic (Rhodopsuedomonas sp.) so this is likely to lead to less Nitrogen being leached and lost in a pastoral system using EM.
The unique mix of micro-organisms in EM will have a major improvement in pond maintenance with the surface crusting broken down and lowering harmful bacterial in ponds. For dairy farms that return their effluent to the pasture, then this is an excellent opportunity to get a double benefit from the EM, by;
The effluent becomes a carrier and a food source for the microbes and the target is the pasture and soil.
The EM will reduce the number of pathogenic microbes (E.coli, etc) in the effluent and make the pasture safer for animals grazing the pasture and staff applying the effluent.

Trials have shown that adding EM to cattle slurry, pig slurry, and pig feed will reduce the levels of greenhouse gas emissions.

A test was done on the height of barley when using regular control versus control mixed with EM
EM applied at 20 litres per ha costs from $20 per ha. I would anticipate that around 100litres per ha per year would be optimum (5*20) that would cost $100 per ha if you expanded EM1 or $210 if you purchased the product Ready to Use. There would be further applications to effluent pond, and possible silage or feed. These costs would have to be calculated after the system is assessed. However the overall cost is not likely to be high relative to the positive gains.
Please note: EM Ready to Use can be made on farm using EM Soil & Crop. Please contact us for details.
EM1 Concentrate is the original and authentic Effective Microorganisms that was originally formulated by Dr. Teruo Higa. EM1 is an all-natural probiotic for plants and soils. EM1 Concentrate is a natural, safe technology with many applications around the Garden, Farm, Vineyard and Environment. A certified organic input, EM1 Concentrate can be expanded by the user to increase the product volume 20 fold, making it a low cost microbial input.
EM® Soil and Crop is a certified organic technology with many applications around farm, orchard, and vineyard environments. This ready to use product works by stimulating soil biology to enhance soil performance and plant production.
EM Environment is a Ready to Use product which is a natural, safe technology with many applications around waste processing, odour, septic systems, compost and water quality. A certified organic product, EM Environment, works by getting the natural processes to function, the way nature intended. This includes breaking down odour, organic matter and sludge, balancing the microbial environment and improving composting activity
EM Amino can be foliar or soil applied on its own or with fertiliser and crop protection products. It is quickly mobilised within the plant to areas where it is most needed. The importance of amino acids is often overlooked in relation to crop results
EM Fulvic is a powerful extract from humates designed to mobilise and naturally chelate elements in the soil
EM Foundation is designed to enhance the activity and longevity of microbial activity in the soil. EM Foundation is a product which combines beneficial soil microorganisms (EM), Amino Acids, Plant Growth Stimulants, and complex food sources in the form of Fish hydrolysate and Humic and Fulvic acid. This combination is designed to stimulate bacteria and fungi, unlock soil bound nutrients and enhance the uptake of fertiliser inputs.
